A Major Flaw in Duolingo (And a way to fix it, kinda)
In a nutshell, most of what you write while practicing a language in duolingo is in your native language, which isn't helpful at all when you're supposed to be learning a different one.
The way I got around this was by practicing my German in the "German to English" course, not vice-versa. This way I had to type more in German than I did in the "English to German" course. Don't know if this works with everyone, it did help me out quite a bit though.
